If You Want to Score Well on the GMAT, You’ve Got to Have a Decent Verbal Score.
A low verbal score will put a hard cap on your total GMAT score. Scoring less than 34 on the verbal portion of the test will prevent you from reaching 700 overall no matter what. If verbal scores are holding back your overall GMAT result, bone up on basic English such as subject-verb agreement before trying to retest.
